J2X Guitar Fret Wire Bender & Unbender

thingiverse

I've been making and selling a fret wire bender on ebay for a year or so but have decided to discontinue making it. That version was made from aluminum and cnc milled. This is a very similar model, but has some printer-friendly changes and requires a few parts be purchased separately. Pictures of the finished product are attached. -To assemble, insert the square nuts in the back of the fret bender. -Slide both bearings onto 1 shoulder bolt then add a spacing washer. Screw it into the square nut from the front side. Do the same thing for the next hole. -For the adjustable roller set, slide 1 bearing onto the shoulder bolt, then add a washer, then slide on the next bearing, then another washer. Now screw it down through the slot into the square nut in the back slot. The tang of the fret wire will ride in the slot between the upper bearing stack. This upper set will be loosened and tightened manually and will act as your adjustment. Here's the shopping list along with McMaster Carr part numbers for reference: M6 Washers to act as spacers (I used 1.0mm thickness in my original, but these can be tricky to find) (Qty 6) - Mcmaster Part: 91166A250 M6x12 Shoulder Bolts for Locating and securing the bearings (Qty 3) - Mcmaster Part: 92981A101 Square Nuts (Qty 3) - Mcmaster Part: 96887A331 626-ZZ Bearings (Qty 6) Pick these up from any ebay seller – a 10 pc lot usually costs $3-$6.
